Wake-up a network mac -- How to do that ?

[Tom Yarmas]

Michel,

If you set the wake on network access option (under energy saver control panel or Battery control panel on Mohave) you can use a wake on LAN command to wake up the Mac. I have not used it , but look at this https://www.cyberciti.biz/faq/apple-os-x-wake-on-lancommand-line-utility <https://www.cyberciti.biz/faq/apple-os-x-wake-on-lancommand-line-utility>

Also, it is pretty easy to use SSH to execute commands like shell scripts on a remote Mac.

But, in the middle of the night, whenever the macBookPro is not fully awake, it does not notice the issuance of the message, until the time the backup is long overdue and CCC issues a last chance instruction to the effect of powering down the backup drive. ns.
